Concept explainers
(a)
Interpretation: The given
Concept introduction: Hydrogenation reaction is exothermic in nature due to the fact that the bonds are stronger in product than in reactant. Heat of hydrogenation can be used as measure for relative stability of alkenes when they are reduced to same
(b)
Interpretation: The given alkenes are to be ranked in order of increasing
Concept introduction: The addition of

Interpretation: The products formed when given alkenes are treated with
Concept introduction: In presence of ozone and
